Two blondes are on a train, sitting in a cabin next to an older gentleman who happens to have a long beard.
One of the blond girls whispers to the other ‘Wow, look, it’s Charles Darwin!!’
‘Are you stupid, he’s been dead for over 200 years!’ the other blonde replies.
Just then, another older man walks into the cabin and says ‘Howdy Charles, I haven’t seen you for hundreds of years, what have you been up to?’
The first blonde says to the second ‘Who’s stupid now?’
